Dear Team, We have purchased the demo for one month and are currently trying to register the VitXi WebRTC. However, we are unable to complete the registration, as the extension remains unregistered. Kindly confirm whether an SSL certificate is required to use WebRTC, even for testing purposes. Please check and advise. ![image](https://forums.vitalpbx.org/uploads/default/original/2X/d/deab289776602ddec78c6a68016702df179697ed.png) ---

Yes, as explained in the wiki, a valid certificate is required for WebRTC to work. > **[VitalPBX Server Preparations  | VitalPBX Wiki](https://wiki.vitalpbx.com/wiki/vitxi/vitalpbx-server-preparations/)** > > For VitXi WebRTC to operate correctly and securely, it is essential that your VitalPBX server is configured with a valid Fully Qualified Domain Name (FQDN) ---
